Choose your substitute based on the dish type and desired flavor match. Use brandy for grape aroma, rum for citrus brightness, vodka for a neutral base, or grappa for intense grape character.
Prepare the substitute as directed: adjust ratios and prep as noted for each option. All substitutes use a 1:1 ratio with the original pisco volume.
Apply the substitution ratio carefully. Start with the stated amount and adjust lime juice or simple syrup in ¼ oz increments after tasting.
Taste and adjust seasoning. Dry shake with egg white for 15 seconds before adding ice, then shake again for 10 seconds to build foam and chill.
